Intel Unveils 50-Watt Quad-core Chips

Intel, the world's largest chip maker, is scheduled to unveil a pair of Xeon quad-core processors with 50-watt thermal envelopes on March 12. Previous chip models had 120 and 80 thermal watt envelopes. The Xeon L5320 ($519 per 1,000 units shipped) and the L5310 ($455 per 1,000 units shipped) have a total of 8MB of L2 cache, use a 1066MHz FSB and offer clock speeds of 1.86GHz and 1.6GHz, respectively. The two chips will work with Intel's Bensley server platform and have been designed to be "drop-in" compatible with existing dual- and quad-core Xeon processors. In a statement, Intel said a number of vendors will start offering these chips, including Acer, Dell, Digital Henge, Fujitsu-Siemens, Hewlett-Packard, HCL Enterprise, IBM, Rackable Systems, Samsung, Verari Systems and Wipro Technologies.

Couple Q's though. Is that $450 for a quad-core CPU with 8 MB cache or for two quad-cores (eg two separate CPUs each with 4 cores .... article mentions sold in pairs)?

And the 60 W envelope, is this peak useage, or 'normal' say 50% of max or something?

That's for 1 CPU, 4 cores, 8MB cache (2MB per core).

And that's peak usage at the clockspeed they're set. As we all know though, they can clock higher, and thus raise the watts.

It's nice that they run cool which would be good for blades and that new supermicro 2 servers in one rack design. I doubt these will BSEL mod well as its probably locked at a much lower voltage and thats how they were binned. Of course you could always mod the voltage pins too but I don't like messing with voltage with physical mods.
